Description

Medical mattress and mattress cover

The present invention is generally directed to a mattress and a mattress cover. More specifically, various embodiments disclose a mattress and mattress cover that is designed to help prevent sudden infant death syndrome (SIDS) and help reduce the risk of oblique head deformities. In various embodiments, the mattress cover also supports many other medical applications when free air flow is required around a subject (eg, for a skin condition or burn patient).

This application is part of a continuation of US Application 12/079,692 filed on March 28, 2008. This application also claims the benefit of U.S. Provisional Application No. 61/301,880 filed on Feb. 5, 2010. The teachings of both of these applications are incorporated herein by reference.

Sudden Infant Death Syndrome (SIDS) is one of the most important causes of infant death in the first year of life. So far, the root cause remains unexplained. However, recent studies have shown a link between SIDS and upper respiratory system blockage. Therefore, many medical authorities today recommend that babies should be supine with their spine straight (so-called straight head position or SHP). The SHP ensures that the upper respiratory system is maximally opened. Thereafter, the tilt position reduces the likelihood of breathing back through the air. The physician further recommends that the infant should be placed so that its torso is slightly raised to reduce the risk of gastroesophageal reflux. Overheating is also a known factor in increasing the risk of SIDS. Choking is a well-known cause of infant death (especially when the child's belly is placed or turned to bed).

Because SIDS poses such a serious threat to babies, it is urgently needed A baby mattress that would help the baby to locate better than the current best practice for reducing SIDS.

In addition, it has been noted that some infants form a flat area (referred to as flat head syndrome or localized oblique head deformity) on the head shell during the first few months due to prolonged lying on a flat, hard surface. Doctors have noticed an alarming increase in the number of cases of oblique head deformities in the past 15 years. This surge has been directly linked to the campaign to allow infants to lie back and sleep to prevent SIDS's 1992 Children's Association's "Back to Sleep" campaign. As more parents adopted these recommendations, the number of cases of oblique head malformations has soared. Therefore, it is desirable to provide a mattress that helps prevent baby's oblique head deformity.

Moreover, some patients (such as burn patients) also need to be surrounded by air; it is desirable to provide free airflow around their injury to allow for better oxygenation and improved scar management, reducing the risk of infection. A mattress with a removable and washable mattress cover that allows for free airflow is a necessity for such patients.

The reference is drawn to FIGS. 1A-1E, which reveals an embodiment of a mattress system 10 that includes a core mattress 20 (with an optional reinforcement system 30) and a mattress cover 40. The core mattress 20 can be further reinforced with the reinforcement system 30 depending on the inherent stiffness or stiffness of the core mattress 20. The reinforcement system 30 prevents the core mattress 20 from bending when under a body weight. In a preferred embodiment, the reinforcement system 30, if present, is disposed within the core mattress 20. The reinforcement system 30 can be made of any suitable material, such as plastic, wood or metal, and can provide a tubular or frame-like structure to strengthen the core mattress 20. In some embodiments the reinforcement system 30 is made of a foam that is more rigid than the surrounding material of the core mattress 20; therefore, the core mattress may include two or more different types of hair The foam body: a first foam which is more elastic and used for filling; and a second foam which is more rigid and serves as the reinforcing system 30.

The core mattress 20 may be made of an elastic material or a plurality of different materials (such as polyurethane foam, polyethylene foam, latex, coconut fiber, cotton, Made of wool, polyester, plastic, carbon, fiberglass, metal or any other suitable material. For example, in some embodiments, the core mattress 20 is made of a polyurethane foam. In other embodiments, the core mattress 20 is formed from a base of a polyester foam on which a second layer of a polyurethane foam is overmolded or glued. In other embodiments, the core mattress 20 is made of natural latex. Other suitable materials having the desired elasticity and stiffness can be used for the core mattress 20 (alone or in combination with the reinforcement system 30). For example, the embodiment core mattress 20 has a base portion 27 made of polyethylene or plastic, and a top portion 29 attached to the base portion 27 and made of polyurethane. However, it should be understood that other changes are possible. For example, the core mattress 20 may have a shell made of an elastic polymer such as polyurethane, latex or the like, which is made of a quilt (such as wool, cotton or another such as a foam). A type of polymer) is filled.

The core mattress 20 has a bottom surface 21 (which can serve as a base for the mattress system 10) and a top surface 23. The top surface 23 is tiltable relative to the bottom surface 21, and thus the body can be lying at an oblique angle relative to the base surface 21 to help prevent gastroesophageal reflux. That is, the height of the core mattress 20 can be increased from a front end 12 to a tail end 14. The angle of inclination can be, for example, from 5 to 30 degrees (20 to 30 degrees is better). The primary system is aligned with the mattress 10 such that the foot faces the front end 12 while the head points toward the higher tail end 14. The core mattress 20 can have a width of about 23 inches to 28 inches from the left side 16 to the right side 18 and about 36 inches from the front end 12 to the tail end 14 by a specific example adapted for use with a child or infant. A length of 39 inches. The core mattress 20 The front end 12 can have a height of about 1 inch to 3 inches while the tail end 14 can have a height of 6 inches to 12 inches. Other embodiments adapted for use, for example, for an adult patient such as a burn patient, may be scaled accordingly, and the reinforcement system 30, if present, may be similarly adjusted accordingly.

At least the top surface 23 of the core mattress 20 is preferably moisture resistant, and the entire core mattress 20 is preferably moisture resistant. Any suitable member can be used to render the core mattress 20 moisture resistant or moisture impermeable. For example, the outer surface 21, 23 of the core mattress 20 can be enclosed (or coated) in an anti-seepage plastic sheet such as a vinyl laminate cover. Additionally, the preferred embodiment core mattress 20 is preferably fire resistant or encased in a fire barrier such as an aromatic polyamide or a para-polyamine synthetic fiber. Such fire barrier layers can be glued or sewn, for example, to the outer surface of the core mattress 20. In a preferred embodiment, the outer surface of the core mattress is also waterproof or gas impermeable. In addition, the outer surface of the core mattress is preferably antifouling.

The top surface 23 of the core mattress 20 includes a recess 22 for receiving, for example, the head or torso of the body. For the purposes of the following, it should be understood that the term "recessed portion" is intended to include two notches in the top surface 23, holes that pass through the core mattress 20, slit sections or regions of the core mattress 20, and Its combination. While the preferred embodiment has only a single recess, it will be appreciated that a plurality of recesses will be known. Furthermore, by using the core mattress 20 for an infant or a child, the recess 22 has a width of about 14 inches and a length of about 17 inches; the tail end 14 of the recess 22 can be combined with the core bed The trailing ends 14 of the pads 20 are spaced approximately 4 inches apart. In a preferred embodiment, the recess 22 is arched (such as a circular, elliptical or similar shape) because such a shape allows the bed The pad system 10 is more resistant to deformation under the weight of the body. However, other shapes such as squares, rectangles, polygons, triangles or the like are of course possible.

The front end 12 of the recess 22 optionally includes a surface 24 that acts as a hip stop for the body. Because the body can be placed in an inclined position, the body may have a tendency to slide toward the front end 12. However, the body can be further partially rested within the recess 22. Thus, the hip stop 24 is used to support the buttocks of the body to prevent any front end of the body from sliding. The hip stop 24 (eg, relative to the bottom surface 21) can have an angle of 20 to 30 degrees. The lower leg and foot of the body may thus rest on the front end 12 of the top surface 23 while the thigh or buttock of the body abuts against the main body. The hip stop 24 and the remainder of the body rest on the bottom surface 25 of the recess 22. , as described in more detail below.

In some embodiments, a removable tray made of, for example, plastic can be disposed within the recess 22 below the body to pick up fluid from the body supported on the recess 22 (such as countercurrent) ()). An absorbent material or the like further lines the tray. Alternatively, the absorbent material may be used only to collect moisture that falls within the recess 22.

For various embodiments, the trailing end 14 of the recess 22 may further include one or more openings 28 in the core mattress 20. However, it should be understood (of course) that the openings 28 can be placed anywhere within the side walls of the recess 22. For example, an opening 28 extending to the bottom surface 21 is provided on the left side 16 and the right side 18 side wall of the mattress 20. Such openings 28 that communicate with the outside (i.e., outside of the recess 22) air or air source may promote air circulation within the recess 22. Additionally, the trailing or outer end 14 of the one or more openings 28 may pass Adaptation is received to receive a supply tube to provide oxygen or aerosol to the body via the recess 22. In some embodiments, one or more of the openings 28 are slits in the core mattress 20. As is well known, oxygen or aerosol can be distributed by wall tubes in a hospital or by a gas cylinder or device; therefore, one or more of the openings 28 can be adapted to be removably with such supply sources A connector that is connected. In this manner, the various embodiments of the mattress 10 can accommodate respiratory conditions of the subject, if any, or promote sustained and thorough oxygen cooperation of the subject to promote, for example, scar treatment and prevent infection.

The mattress cover 40 covers the top surface 23 of the core mattress 20 and, in some embodiments (as shown in FIG. 1), surrounds the entire core mattress 20. The mattress cover 40 is preferably fire and dirt resistant. Some embodiments may include one or more anchoring devices 41 at the front end 12, the trailing end 14, the left end 16, or the right end 18, as appropriate to provide for securing the cover 40 to the core 20 or to an external device (such as An anchoring system for a crib. Any suitable anchoring device can be used, such as a strap, snap, hook, hook and loop fastener or the like. For example (as shown in Figure 1C) the anchoring device 41 can be attached to the outer surface of the mattress cover 40 and used to mechanically couple to the slats 2 of the crib. Thus, when placed under tension from a body, the mattress cover 40 can transmit the tension to the slats 2 by the anchoring device 41; the anchoring device 41 can thereby prevent the cover 40 from being Excessive deformation under the weight of the main body. Similarly (as shown in FIG. 1D), an embodiment core mattress 20 may include anchoring means 49 to distribute the load of the core to the core mattress 20 and thereby prevent the core mattress 20 Excessive deformation. The anchoring device 49 provides an anchoring system that is coupleable to an outer surface of the core mattress 20 and passes through an opening 43 in the mattress cover 40 for attachment to a slat 2 such as a crib An external device. The mattress cover 40 can thus comprise an opening 43 in which the corresponding anchoring means 49 are registered on the core mattress. The anchoring means 41, 49 also prevents the creation of a dangerous gap between the top end of the mattress and the crib and thereby prevents the baby from crawling and suffocating under the mattress.

In the preferred embodiment, the mattress cover 40 has a bag-like shape having an opening that can be closed by a closure mechanism 48 such as a zipper, button, hook and loop fastener or the like. 45. In some embodiments, the closure mechanism 48 can be a flap for closing over or around the opening 45 of the core mattress 20, as in the case of a pillow to maintain a pillow in the same manner. The shape of the mattress cover 40 is modified to form a particular shape of the core mattress 20 to better fit the cover 40 to the core 20. The mattress cover 40 of the preferred embodiment thus has a bottom surface and a top surface that can serve as a base for the mattress system 10. The top surface may be at least partially inclined relative to the bottom surface, conforming to the inclination of the core mattress 20 to which the cover 40 is intended to be closely fitted, and thereby the body may be inclined at an angle relative to one of the base surfaces Lying down to help prevent reflux of the gastroesophageal tract.

In a preferred embodiment, regardless of the actual shape of the mattress cover, the mattress cover is easily removed from the core mattress to facilitate cleaning of the mattress cover. Therefore, the mattress cover is also easy to reattach to the core mattress to facilitate reuse of the mattress cover after cleaning. For example, because of the closable opening 45, the cover 40 is easily removed from the core 20 for cleaning. In particular, the core mattress 20 can be removed through the opening 45, which can then be washed (eg, by placing it in a standard washer or the like), dried and then reinstalled back Close or close on the core mattress 20 and close the closure Mechanism 48 secures the cover 40 to the core mattress 20.

In the preferred embodiment, the mattress cover 40 is formed from two different types of fabric for the corresponding regions of the core mattress 20. The cover 40 includes a web of material 44 that is positioned such that it is disposed across the recess 22 when mounted on the core mattress 20. The mesh material 44 is used as a hammock on which the main system lies (completely or partially), supported and suspended on the bottom surface 25, and is, for example, directly accessible to one of the soft materials of the body (such as cotton) Made of polyester, nylon, coconut fiber or hemp yarn. The web material 44 can have, for example, substantially the same shape as the recess 22 to which the web material 44 is mounted. For the purposes of the following, "mesh" means a fabric (such as a mesh, netting or the like) having repeating holes or openings. The web material 44 provides a highly gas permeable interface to the body to ensure maximum circulation of one of the oxygenated air surrounding the body and further permit drainage of liquid from the body. By way of example, the web material 44 for an infant can have a width of about 14 inches and a length of about 20 inches; the trailing end 14 of the web material 44 can be associated with the tail end of the mattress cover 40. 14 is about 4 inches apart. In some embodiments, the mesh material 44 will receive the head or torso or the entire body of the body.

For such portions of the web material 44 in contact with the body, the width of the gap in the woven material constituting the web material 44 is less than the width of the fingers of the body; for example, in the preferred embodiment, The mesh opening will not allow the passage of a rod having a full radius tip of 0.250 inch diameter. In certain embodiments, the mesh material 44 can further comprise a reinforcing mesh that is not directly in contact with one of the bodies, the mesh can be made of a stronger material such as nylon. production. Thus, the web material 44 can be formed from two separate materials: a soft upper material on which the body lies in direct contact, the material having a relatively narrow gap of woven material (i.e., less than the fingers of the body) Width); and the body is not in direct contact with one of the optional lower reinforcing meshes that provides additional support for the mesh material 44.

In some embodiments, if there is a stronger reinforcing material for the web material 44, it can be attached to the (for example, by a zipper, snap, hook, and loop fastener or the like) The mattress core 20 around the recess 22 reinforces the upper surface of the web material 44 provided by the topmost softer web material 44. In still other embodiments, the remainder of the cover 40, which is the remainder of the web material removed from the cover 40, may also have an additional mesh fabric to provide reinforcement for the weight of the body. The lower reinforcing mesh is removably attached to the core mattress 20 by any suitable attachment mechanism. Alternatively, the lower reinforcing mesh can be attached to the mattress cover 40 itself. In some embodiments, the lower reinforcing mesh also extends over the remaining portion 42 of the cover 40 (which is external to the mattress recess 22) to provide access to the entirety of the cover 40 or the top surface of the cover 40. Strengthening. All or most of the remainder 42 of the cover 40 may be made of another type of fabric, such as standard cotton, poly-cotton or the like, and corresponding to the core external to the recess 22 The body mattress 20 is attached to the areas of the perimeter of the web material 44. In still other embodiments, the web material 44 can be made of a breathable fabric that is not a mesh material such as woven polyester or nylon.

The web material 44 of the cover 40 allows fluid from the body to easily fall onto the bottom surface 25 of the recess 20 (such as into a catchment area) without gathering In the cover 40. The mesh material 44 also ensures that the maximum amount of air flow that can be used for the body (which is especially important if the body has been turned over) is helpful to help reduce SIDS and help burn patients to heal and prevent infection and can be advised Used in the treatment of certain skin diseases. The curvature of the mesh material 44 can also help prevent oblique head deformities. The air flow from the opening 28 helps to avoid re-inhalation of air. Such openings 28 may also permit management of the therapeutic amount of oxygen or aerosol. The cover 40 can further incorporate additional sections of mesh or gas permeable material 46 that are positioned to register with the openings 28 in the core mattress 20 to ensure maximum circulation of air within the recess 22.

As is known, oxygen or aerosol can be distributed by wall tubes in a hospital or by a gas cylinder or device; one or more of the openings 28 can thus be adapted to mate with such supply sources Connector. Thus, one or more of the openings in the mattress cover 40 can be reinforced with a connector such as one of the adapters 47. For example, the cover 40 can further include an adapter 47 that is sewn or otherwise directly coupled to the cover 40 for mating with the gas supply hose and the opening 28. Alternatively, the cover 40 can simply have apertures that are aligned with the openings 28 rather than the gas permeable material 46. Variations in the two are also possible, with some of the openings 28 being covered by the gas permeable material 46 and others being exposed by corresponding holes in the cover 40. Additionally, a ventilator, such as an electric ventilator, can be disposed in the mattress core 20 to help renew and circulate air within the recess 22 and increase airflow through the mesh material 44. The ventilator can be coupled to an opening 28, for example, via an air hose, or even with the opening 28 itself. In this manner, the various embodiments of the mattress can be adapted to the patient's respiratory disease (or dermatological condition), if any.

The mesh material 44 (including any underlying support layer (if present)) is preferably modified to conform to the hip stop 24 such that when the body lies in a hammock provided by the mesh material 44, the body The buttocks can rest comfortably against the stop surface 24. The web material 44 is less deformable than the core mattress 20 and thus requires a lower support woven material to reinforce the soft upper woven material of the web material 44 in contact with the body. Alternatively (as previously discussed) an anchoring system 41 can be provided to assume some of the stress imparted by the weight of the body and disperse it to another mechanical component, such as a crib, bed frame or the like.

As mentioned above, in some embodiments the mattress system provides a sloping top surface comprising a hammock on which the primary system is placed and suspended over a recess. Due to the sloping nature of the top surface, the body may tend to slide toward the trailing end of the mattress system. Thus, in some embodiments the mattress cover 40 may include a seat belt or the like that can be used to prevent the body from sliding toward the trailing end of the core mattress. Any suitable seat belt system known in the art (such as a conventional child seat belt) can be used.

As shown, the core mattress 20 may be deformed under the weight of the body. The depth of the web material 44 (i.e., the distance the web material 44 extends into the recess 22) may thus form the width of the web of the web material 44, the elasticity of the web material 44 (and any underlying reinforcement). The net combination), the width of the recess 22, and the elasticity of the core mattress 20. Thus, in embodiments in which the core mattress 20 is easily deformable under the weight of the body, it may be desirable to have the mesh material 44 disposed relatively tightly on the recess 22 so as to be under the weight of the body. The final desired curvature of the web material 44 is achieved. example For example, the web material 44 may initially be flat, but will then bend under the weight of the body. Alternatively, by way of example, the length of the anchoring system component 41 is designed to prevent the web material 44 from extending into the recess 22 beyond a predetermined distance.

In some embodiments, the bottom surface 25 of the core mattress 20 within the recess 22 can have a secretion passage for fluid removal; in such embodiments, the depression can be in the core mattress 20. A suitable slit or opening is made in any of the side walls of portion 22 to effect removal of such secretions.

The web material 44 bonded to the mattress recess 22 by the mesh or breathable fabric and the underlying reinforced mesh or breathable fabric (if present) ensures that a maximum amount of clean fresh air is provided to the web The subject believes that clean fresh air helps prevent SIDS and helps treat various skin conditions, injuries or both. The conformal curvature of the mesh material 44 and a baby's head shell can also help prevent oblique head deformities. The mattress system 10 vents to allow gas to flow, which reduces sweating of the subject. Moreover, liquids such as milk, urine, vomit or the like will fall through the (web) fabric.

Variations on the embodiments disclosed above are discussed below. As shown in Figure 2, in some embodiments the top surface of the core mattress can be parallel to the bottom surface of the core mattress, and the mattress cover can be adapted accordingly to provide one of the surrounding of the core mattress work close with.

The preferred embodiment uses a mattress cover that completely encloses the core mattress. However, this is not required. 3 is an exploded perspective view of another mattress system 50 including a core mattress 51 having a recess 52, a reinforcement system 54 and a mattress cover 59. The mattress cover 59 comprises a breathable (preferably mesh system) A preferred hammock portion 58 that can be disposed within a second fabric; and a mattress cover anchoring system 57 for coupling to the core mattress 51. The core mattress 51 also includes a core mattress anchoring system 56 that is configured to couple with the mattress cover anchoring system 57. The core mattress anchoring system 56 and the mattress cover anchoring system 57 can be zippers, hook and loop fasteners, snaps, hooks and holes, straps or the like. For example, a hook that is inserted into the side of the mattress 51 as a core mattress anchoring system 56 can receive corresponding holes in the mattress cover 59 as the mattress cover anchoring system 57; or, for example, for example One half of a zipper can be attached to the mattress core 51 and corresponds to the other half of the zipper attached to the removable mattress cover 59. The recess 52 can be elliptical and can receive an annular, elliptical reinforcement system 54 around its perimeter that prevents the sidewalls of the recess 52 from sagging or collapsing. The reinforcement system 54 is made of any suitable material to impart greater stiffness to the side walls of the recess 52. As in the previous embodiment, the core mattress 51 can include an opening 53 to facilitate recirculation of air within the recess 52.

In an alternative to the system 50 of the above embodiment, the mattress cover can be designed to completely cover a fitted sheet of the top and side edges of the core mattress and partially extend to the underside of the core mattress. The mattress cover of this embodiment may comprise, for example, an elastic material sewn into the corners of the cover, the elastic material acting as an anchoring system to elastically couple the mattress cover to the core mattress and This is thus maintained in position on the core mattress.

4 is an exploded perspective view of another embodiment of the mattress system 60 similar to the embodiment 50. However, while the embodiment system 50 has a core mattress having an inclined top surface, the core mattress of the system 60 has a large The body is parallel to a top surface of the bottom surface.

In various embodiments of the mattress system, the core mattress can be provided by a frame structure and can provide a corresponding mattress cover for the frame structure. For example (as shown in Figure 5) an embodiment frame structure 70 includes a series of supports 72 that may be made of any suitable rigid material, such as plastic, wood, metal or the like, and which may be made of, for example, cotton. A filler of wool, foam, rubber or the like is covered to provide a resilient surface. The frame 70 may have a triangular shape to provide a sloping top surface 74 relative to one of the bottom surfaces 76. An embodiment of the mattress cover can be provided to completely enclose the frame, wherein the central portion of the frame 70 acts as a recess 79 on which the hammock is suspended by the support members 72.

Another embodiment frame 80 is depicted in FIG. 6, which is adapted for use with an embodiment of a mattress cover that does not completely enclose the frame 80. The frame system 80 is similar to the embodiment of Figure 5 and includes a fill support 82 in the form of a triangle. However, an anchoring system 86 is provided along one of the support members 82, one of the support members 82 for removably coupling to one of the corresponding anchoring systems of the mattress cover of the embodiment, As described above, it is described in the previous embodiment. The anchoring system 86 preferably extends around the entire perimeter of the frame 80. Thus, when the mattress cover is suspended over the recess 89, the anchoring system 86 receives the load from the mattress cover.

One embodiment of the frame system 90 is substantially identical to the embodiment frame system shown in FIG. 5, but the top surface 94 is generally parallel to the bottom surface 96. Similarly, one embodiment of the frame system 100 is substantially identical to the embodiment frame system shown in FIG. 6, but the top surface 104 is large. The body is parallel to the bottom surface 106.

In some embodiments, the core mattress can comprise a frame structure combined with a relatively thin mattress filler as described above, the relatively thin mattress filler being coupled to a top surface defined by the frame structure. For example, (as shown in FIG. 9) a frame structure 102 (such as disclosed in FIG. 5) is used to support a thin mattress fill 104. The mattress padding (e.g., made of polyurethane foam or coconut fiber) 104 includes a hole 105 (which incorporates an open area 106 provided by the frame 102) that provides the recess for an example mattress cover. unit. The mattress filler 104 can be attached to the frame 102 by a complementary shape or by means of glue, tape, hook and loop fasteners, buttons or any other suitable anchoring system. In some embodiments, the mattress pad 104 and the frame 102 can be enclosed in a mattress quilt. An embodiment mattress cover can then completely enclose the core mattress 110 provided by the frame 102 and the filler 104 to provide an embodiment mattress system.

The embodiment of the mattress core 120 shown in FIG. 10 is substantially identical to the embodiment of the mattress core described above with reference to FIG. 9, except that instead of one of the frames 122 shown in FIG. In this case, a mattress cover similar to one of the core mattresses 120 may be used instead of using one of the mattress covers similar to that described with reference to FIG. In particular, the core mattress 120 includes an anchoring system 126 coupled to one of the mattress covers to removably secure the mattress cover to the frame 122. Thus, the mattress cover of this embodiment for the core mattress 86 can cover only the top surface of the core mattress and a portion of the side walls.

One embodiment of the core mattress 130 is shown in FIG. The embodiment core mattress is substantially identical except that it has a top surface that is parallel to the bottom surface of the core mattress, rather than being tilted as in Figure 9. Similarly, the core mattress 140 shown in Figure 12 is generally similar to the core mattress shown in Figure 10, but again has a substantially parallel top and bottom surface.

Figure 13 illustrates another method used by a core mattress to provide the recess. The core mattress 150 includes a U-shaped cutout region 152 that provides the recess 158 and that effectively forms wings 154, 156 on the core mattress 150 that extend toward the core mattress 150. The tail end and the hammock are suspended between the wings 154, 156 by means of an embodiment of a mattress cover. The U-shaped cut region 152 ensures a maximum amount of recirculation within the recess 158. Thus, an embodiment of the mattress cover can include a mesh or other breathable fabric that wholly or partially covers the trailing end 159 of the U-shaped slit 152. A reinforcement system can be used in the core mattress 150 to reinforce the wings 154, 156, for example by extending a U-shaped support along the sidewalls of the recess 158, extending through the wings 154, 156 and so on.

In some embodiments of the core mattress (as shown in Figure 14), a spring 162 (as is conventional) may be used to provide the desired elasticity of the core mattress 160 rather than using the foam as disclosed above or Being quilted. In addition, as shown in Fig. 14, the entire top surface of the one-core mattress does not have to be at the same inclination angle. For example, the front end 164 can be tilted (as disclosed in the above embodiments), but the trailing end 166 can be flat (i.e., parallel to the bottom surface 161). The transition line 165 between the sloped top surface 164 and the flat top surface 166 can be, for example, along a line in the recess 167. However, other locations of the transition line 165 are of course possible. It will be understood that this type of multi-angle tilt of the top surface of the core mattress can be Used in any of the above embodiments.

Although the invention has been described with reference to the particular embodiments thereof, it is understood that these embodiments are merely illustrative of the principles and applications of the invention. Therefore, it is to be understood that various modifications may be made in the embodiments of the invention, and the scope of the invention is defined by the scope of the invention.
